There is a reason Sandra Bullock is America's Sweetheart and it's not just because she tends to be cast in roles that make us love her. She seems to be 700 kinds of awesome, and an amazing mother to top it all off. Her latest film, Gravity, which is getting glowing reviews from just about everybody, was a very challenging role but it was what was going on in Sandra's personal life that had the potential to end her chance of playing a medical engineer and first-time astronaut Ryan Stone who ends up adrift in space.

It has to be a great time for my son. I can't miss him. If I miss him, I will be of no use to you.

I love her. And she's so right. There's this weird thing that happens when you become a parent. When you are with your kids a lot, you definitely need a break -- even just to grab a cup of coffee and stare at the clouds. But then when you do get that break and are away from them, you miss them. When the filming was taking place, Louis was just learning to walk and there was no way Sandra was going to miss that. She was filming in London, far from her home in Austin, Texas, and Louis was able to come along. That would have been a huge chunk of time to be away from her child, and I love that Cuaron had no issue with it. Then again, he did write the screenplay with his own son, Jonas.

Sandy added:

You know, he's just learning how to walk. So guess what's going to happen? 'I have to go! He's taking steps!' Everyone cooperated in that department. It was a family film. Everyone had kids. So everyone knew the value of that. So they said, 'If we make it amazing for him right where you are, will you be okay?' And I said, 'Yeah.'

It's clear Sandra is a very involved, hands-on kind of mother. I love how she puts family first, and was willing to risk losing a role of a lifetime to staying home with her son. But as we know, seeing your child grow and learn and take their first steps or say their first words ... those are the moments -- moments that warm your heart -- that are truly priceless and what life is all about.

What do you think of Sandy's demands of being with her son while filming? Do you think more of Hollywood should do the same? More employers everywhere?
